RELATED APPLICATION

This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 62/737,041, filed Sep. 26, 2018, the content of which is incorporated herein by reference in its entirety.

BACKGROUND

The Colorado potato beetle (Leptinotarsa decemlineata) is a major pest of the potato crop. The annual costs of controlling the Colorado potato beetle are estimated to be in the tens of millions of dollars, with projected annual costs of crop loss reaching billions of dollars if the Colorado potato beetle is left uncontrolled. Moreover, controlling the Colorado potato beetle is complicated by its resistance to numerous chemicals and insecticides. Accordingly, new ways of controlling the Colorado potato beetle are needed.

SUMMARY

The present disclosure provides, in some aspects, compositions, genetic constructs, and methods for controlling Colorado potato beetle infestation. To reduce our dependence on broad-spectrum chemical insecticides and their related problems, reduced-risk pesticides are required. A new technology that offers the promise of a reduced risk approach to insect pest control is RNA interference (RNAi). In some embodiments, the present disclosure provides RNAi-based technologies that can mitigate Colorado potato beetle damage by delivering ribonucleic acid (RNA) interference (RNAi) molecules that target (e.g., bind to) and interfere with the messenger RNA (mRNA) of a Colorado potato beetle Inhibitor of Apoptosis (IAP) gene.

Apoptosis is an evolutionarily conserved pathway of cell suicide that is critical for normal cell development and homeostasis. The key regulators of apoptosis are IAPs. IAPs were discovered in insect baculoviruses (Cydia pomonella granulosis virus and Orgyia pseudotsugata nuclear polyhedrosis virus) and have since been identified in many other organisms, such as mosquito iridescent viruses, insects, yeast, and human. Many IAPs block apoptosis when they are overexpressed in cells of other species. Knockdown expression of IAPs through RNA interference typically induces apoptosis. See, e.g., Pridgeon J W et al. J Med Entomol 2008; 45(3): 414-420.

Laboratory studies have confirmed that oral delivery of RNA molecules whose mode of action is through the RNAi process (e.g., double-stranded RNA (dsRNA)) are effective for many insect species and hence, topical dsRNA is considered a suitable form of delivery. However, spray-on dsRNA insect pest control technology does not exist today. The cost of production of dsRNA at relatively low price is a major challenge for the Ag-Bio industry. For agricultural pests, transgenic plants that can express insecticidal dsRNA may protect the plants from insect herbivory. However, not all countries are receptive to genetically-modified crops, and spray-on application of dsRNA is being considered as an alternative delivery method of protection.

To identify targets for RNAi knockdown, whole genome information was used to identify the appropriate gene sequence for TAP in the target species (Leptinotarsa decemlineata), which when silenced selectively, controls these key pests, without adversely affecting non-target species in the potato agriculture ecosystem. Given a DNA sequence of interest and a rule set of design criteria for the output sequences, a propriety computational algorithm was combined with publicly available RNAi design tools, to create output sequences that meet these criteria. The original/initial region selected to design the dsRNA was identified by searching comprehensive sequence databases for Tribolium and Drosophila genomes (e.g., Flybase, SnapDragon, Beetlebase, etc.). The publicly available E-RNAi tool, that can be used to design dsRNA using a predicted siRNA-based approach, was combined with proprietary algorithms to create the design workflow. This design workflow was then used to create specific long dsRNA sequences of a (a) desired length (b) desired percent identity to original sequence (by introducing random mutations), and (c) by sectioning the initial TAP gene sequence into multiple fragments.

In some embodiments, the RNAi molecules comprise single-stranded RNA (ssRNA), and in some embodiments, the RNAi molecules comprise double-stranded RNA (dsRNA) or partially dsRNA. In still other embodiments, the RNAi molecules may be single-stranded RNA molecules with secondary structure containing significant double-stranded character, such as, but not limited to, hairpin RNA. The present disclosure provides RNA, for example single stranded RNA (ssRNA), small interfering (siRNA), micro RNA (miRNA), messenger RNA (mRNA), short hairpin (shRNA) or double stranded RNA (dsRNA) for targeting IAP mRNA.

IAP RNA, in some embodiments, is effective for reducing IAP expression in an insect, stunting of larvae, inhibiting growth, reproduction (e.g., fertility and/or fecundity) and/or repair of the insect, killing of the larvae or the insect, and decreasing feeding of the insect. Accordingly, one aspect of the present disclosure provides a method for controlling an insect comprising delivering (e.g., contacting) an effective amount of an IAP-targeting RNA with a plant and/or an insect. IAP RNA is particularly useful for controlling a Coleopteran insect (e.g., Colorado potato beetle), thereby reducing and/or preventing infestation of certain plants (e.g., a potato) that are a major food source for humans.

Some aspects of the present disclosure also provide cell-free methods of producing IAP-targeting RNA, the method comprising: (a) incubating in a reaction mixture cellular RNA, and a ribonuclease under conditions appropriate for the production of 5′ nucleoside monophosphates (5′ NMPs); (b) eliminating the ribonuclease; and (c) incubating the reaction mixture, or in a second reaction mixture, the 5′ NMPs, a polyphophospate kinase, a polyphosphate, a polymerase, and a DNA (also referred to a DNA template) under conditions appropriate for the production of the TAP-targeting RNA from the DNA.

Also provided herein are compositions comprising an TAP-targeting RNA. In some embodiments, the composition comprising an TAP-targeting RNA further comprises an additive, for example, a chemical, a pesticide, a surfactant, a biological, or other non-pesticidal ingredient. In some embodiments, TAP-targeting RNA is provided in an expression vector. In some embodiments, an TAP-targeting RNA is provided in a plant or a plant cell.

It should be understood that an “RNAi molecule targeting TAP” encompasses “RNAi molecules targeting mRNA encoded by TAP.” A RNAi molecule is considered to target a gene of interest if the RNAi molecule binds to (e.g., transiently binds to) and inhibits (reduces or blocks) translation of the mRNA, e.g., due to the mRNA being degraded. In some embodiments, if there are epigenetic changes, a RNAi molecule may inhibit expression of the mRNA encoded by the gene of interest. It should also be understood that in some embodiments, the polynucleotide is a double-stranded RNA (e.g., dsRNA GS3) that inhibits expression of a coding region of the gene (e.g., TAP). In other embodiments, the polynucleotide is a DNA sequence that encodes a dsRNA. In yet other embodiments, the polynucleotide is an antisense RNA. It should be understood that the sequences disclosed herein as DNA sequences can be converted from a DNA sequence to an RNA sequence by replacing each thymidine with a uracil.

RNAi Molecule Targeting Inhibitor of Apoptosis (IAP)

RNAi molecules targeting IAP have been identified through examination of IAP mRNA and in vivo (e.g., plant/field) testing. Such RNAi molecules targeting IAP are useful for controlling Coleopteran insects (e.g., Colorado potato beetles), for example, by inhibiting or reducing expression of IAP, and consequently, by increasing insect mortality, as well as decreasing growth, reproduction (e.g., fertility and/or fecundity), and/or feeding (e.g., eating and/or drinking) of Coleopteran insects.

Expression of a gene in a cell (e.g., insect cell), for example, is considered to be inhibited or reduced through contact with an RNAi molecule if the level of mRNA and/or protein encoded by the gene is reduced in the cell by at least 10% relative to a control cell that has not been contacted with the RNAi molecule. For example, delivering to a cell (e.g., contacting a cell) with an RNAi molecule (e.g., dsRNA) targeting IAP may result in a reduction (e.g., by at least 10%) in the amount of RNA transcript and/or protein (e.g., encoded by the IAP gene) compared to a cell that is not contacted with RNAi molecular targeting IAP.

In some embodiments, RNAi molecules of the present disclosure specifically inhibit expression of an IAP gene without biologically relevant or biologically significant off-target effects (no relevant or significant change in the expression of non-IAP genes). In some embodiments, an RNAi molecule specifically inhibits (reduces or blocks) translation of an IAP protein by specifically inhibiting expression of (e.g., degrading) an IAP mRNA (e.g., IAP mRNA of SEQ ID NO: 19) that encodes the IAP protein. Specific inhibition of an IAP gene includes a measurable reduction in IAP gene expression (e.g., IAP mRNA expression, and/or IAP protein expression) or a complete lack of detectable gene expression (e.g., IAP mRNA expression, and/or IAP protein expression).

In some embodiments, RNAi molecules of the present disclosure specifically inhibit expression of an IAP gene without biologically relevant or biologically significant off-target effects (no relevant or significant change in the expression of non-IAP genes). In some embodiments, an RNAi molecule specifically inhibits the expression of an IAP protein by specifically inhibiting an mRNA that encodes an IAP protein (e.g., IAP mRNA of SEQ ID NO: 19). Specific inhibition of an IAP gene involves a measurable reduction in IAP gene expression (e.g., IAP mRNA expression, and/or IAP protein expression) or a complete lack of detectable gene expression (e.g., IAP mRNA expression, and/or IAP protein expression).

RNAi molecules targeting IAP provided herein, in some embodiments, are designed to have complementarity to IAP mRNA of a Coleopteran insect, e.g., a Colorado potato beetle. An example of a DNA sequence encoding Colorado potato beetle IAP is provided in the sequence of SEQ ID NO: 1. An example of an mRNA sequence encoding Colorado potato beetle IAP is provided in the sequence of SEQ ID NO: 19.

In some embodiments, the RNAi molecule targeting IAP provided herein is designed to have complementarity to IAP mRNA of a Leptinotarsa insect, e.g., a Leptinotarsa decemlineata (a Colorado potato beetle), a Leptinotarsa behrensi, a Leptinotarsa collinsi, a Leptinotarsa defecta, a Leptinotarsa haldemani (a Haldeman's green potato beetle), a Leptinotarsa heydeni, a Leptinotarsa juncta (a false potato beetle), a Leptinotarsa lineolata (a burrobrush leaf beetle), a Leptinotarsa peninsularis, a Leptinotarsa rubiginosa, a Leptinotarsa texana, a Leptinotarsa tlascalana, a Leptinotarsa tumamoca, and/or a Leptinotarsa typographica.

A double-stranded RNA (dsRNA) of the present disclosure, in some embodiments, comprises a first strand that binds to (e.g., is at least partially complementary to or is wholly complementary to) a messenger RNA (mRNA) encoded by a Coleopteran IAP gene, and a second strand that is complementary to the first strand.

dsRNA may comprise RNA strands that are the same length or different lengths. In some embodiments, a dsRNA comprises a first strand (e.g., an antisense strand) that is the same length as a second strand (e.g., a sense strand). In some embodiments, a dsRNA comprises a first strand (e.g., an antisense strand) that is a different length than a second strand (e.g., a sense strand). A first strand may be about 1%, 2%, 3%, 4%, 5%, 10%, 15%, 20%, or more than 20% longer than a second strand. A first strand may be 1-5, 2-5, 2-10, 5-10, 5-15, 10-20, 15-20, or more than 20 nucleotides longer than a second strand.

dsRNA molecules can also be assembled from a single oligonucleotide in a stem-loop structure, wherein self-complementary sense and antisense regions of the RNA molecule are linked by means of a nucleic acid based or non-nucleic acid-based linker(s), as well as circular single-stranded RNA having two or more loop structures and a stem comprising self-complementary sense and antisense strands, wherein the circular RNA can be processed either in vivo or in vitro to generate an active RNAi molecule capable of mediating RNAi. An RNAi molecule may comprise a 3′ overhang at one end of the molecule. The other end may be blunt-ended or have also an overhang (5′ or 3′). When the RNAi molecule comprises an overhang at both ends of the molecule, the length of the overhangs may be the same or different.

A single-stranded RNA of the present disclosure, in some embodiments, comprises a strand that binds to a mRNA encoded by a Coleopteran IAP gene.

RNAi molecules targeting IAP as provided herein may vary in length. It should be understood that, in some embodiments, while a long RNA (e.g., dsRNA or ssRNA) molecule is applied (e.g., to a plant) as the insecticide, after entering cells this dsRNA is cleaved by the Dicer enzyme into shorter double-stranded RNA fragments having a length of, for example, 15 to 25 nucleotides. Thus, RNAi molecules of the present disclosure may be delivered as 15 to 25 nucleotide fragments, for example, or they may be delivered as longer double-stranded nucleic acids (e.g., at least 100 nucleotides).

Thus, in some embodiments, RNAi molecules targeting IAP comprise 15-1564 nucleotides (ssRNA) or nucleotide base pairs (dsRNA). For example, an RNAi molecule of the present disclosure may comprise 15-1000, 15-950, 15-900, 15-850, 15-800, 15-750, 15-700, 15-650, 15-600, 15-500, 15-450, 15-400, 15-350, 15-300, 15-250, 15-200, 15-150, 15-100, 15-50, 19-1000, 18-950, 18-900, 18-850, 18-800, 18-750, 18-700, 18-650, 18-600, 18-500, 18-450, 18-400, 18-350, 18-300, 18-250, 18-200, 18-180, 18-100, 18-50, 19-1000, 19-950, 19-900, 19-850, 19-800, 19-750, 19-700, 19-650, 19-600, 19-500, 19-450, 19-400, 19-350, 19-300, 19-250, 19-200, 19-190, 19-100, 19-50, 20-1000, 20-950, 20-900, 20-850, 20-800, 20-750, 20-700, 20-650, 20-600, 20-500, 20-450, 20-400, 20-350, 20-300, 20-250, 20-200, 20-200, 20-100, 20-50, 15211000, 21-950, 21-900, 21-850, 21-800, 21-750, 21-700, 21-650, 21-600, 21-500, 21-450, 21-400, 21-350, 21-300, 21-250, 21-210, 21-210, 21-100, 21-50, 22-1000, 22-950, 22-900, 22-850, 22-800, 22-750, 22-700, 22-650, 22-600, 22-500, 22-450, 22-400, 22-350, 22-300, 22-250, 22-220, 22-220, 22-100, 22-50, 23-1000, 23-950, 23-900, 23-850, 23-800, 23-750, 23-700, 23-650, 23-600, 23-500, 23-450, 23-400, 23-350, 23-300, 23-250, 23-230, 23-230, 23-100, 23-50, 24-1000, 24-950, 24-900, 24-850, 24-800, 24-750, 24-700, 24-650, 24-600, 24-500, 24-450, 24-400, 24-350, 24-300, 24-250, 24-240, 24-240, 24-100, 24-50, 25-1000, 25-950, 25-900, 25-850, 25-800, 25-750, 25-700, 25-650, 25-600, 25-500, 25-450, 25-400, 25-350, 25-300, 25-250, 25-250, 25-250, 25-100, or 25-50 nucleotides or nucleotide base pairs. In some embodiments, RNAi molecules targeting TAP comprise or consist of at least 15, at least 16, at least 17, at least 18, at least 19, at least 20, at least 25, at least 50, at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, or at least 1000 nucleotides or nucleotide base pairs.

In some embodiments, an RNAi molecule targeting TAP comprises or consists of a sequence that is complementary to an mRNA or a segment of an mRNA encoded by a Coleopteran TAP gene.

In some embodiments, an RNAi molecule targeting TAP comprises or consists of a sequence that is complementary to an mRNA encoded by a region or segment of a Coleopteran TAP DNA. In some embodiments, an RNAi molecule targets an mRNA encoded by a 5′ region or segment of a Coleopteran TAP DNA. A 5′ region of a Coleopteran TAP DNA may comprise or consist of any sequence encompassed by nucleotides 1 to 600, nucleotides 10 to 600, nucleotides 25 to 600, nucleotides 50 to 600, nucleotides 100 to 600, nucleotides 150 to 600, nucleotides 200 to 600, nucleotides 250 to 600, nucleotides 300 to 600, nucleotides 350 to 600, nucleotides 400 to 600, nucleotides 450 to 600, or nucleotides 500 to 600 of the TAP DNA (e.g., nucleotides 1-600 of SEQ ID NO: 1). In some embodiments, an RNAi molecule targets an mRNA encoded by a central region or segment of a Coleopteran TAP DNA. A central region of a Coleopteran TAP DNA may comprise or consist of any sequence encompassed by nucleotides 400 to 1200, nucleotides 450 to 1200, nucleotides 500 to 1200, nucleotides 550 to 1200, nucleotides 600 to 1200, nucleotides 650 to 1200, nucleotides 700 to 1200, nucleotides 850 to 1200, nucleotides 900 to 1200, nucleotides 950 to 1200, nucleotides 1000 to 1200, nucleotides 1050 to 1200, or nucleotides 1100 to 1200 of the IAP DNA (e.g., nucleotides 400-1200 of SEQ ID NO: 1). In some embodiments, an RNAi molecule targets an mRNA encoded by a 3′ region or segment of a Coleopteran IAP DNA.

It should be understood that the term gene encompasses coding and non-coding nucleic acid. Thus, in some embodiments, an IAP gene encodes an mRNA that comprises a 5′ untranslated region, an open reading frame, and a 3′ untranslated region. Thus, an RNAi molecule herein, in some embodiments, binds to a 5′ untranslated region, an open reading frame, and/or a 3′ untranslated region of an mRNA.

The “percent identity” of two nucleic acid sequences (e.g., RNAi molecules targeting IAP provided herein and any one of, for example, SEQ ID NOS: 1, 19, or 37) may be determined by any method known in the art. The variants provided herein, in some embodiments, contain randomly placed mutations with the four nucleotides (A, U, G, C) selected at an approximately equal probability for a given mutation. In some embodiments, these mutations might be distributed either over a small region of the sequence, or widely distributed across the length of the sequence. In some embodiments, the percent identity of two nucleic acid sequences is determined using the algorithm of Karlin and Altschul, Proc. Natl. Acad. Sci. USA 87:2264-68, 1990, modified as in Karlin and Altschul, Proc. Natl. Acad. Sci. USA 90:5873-77, 1993. Such an algorithm is incorporated into the NBLAST and XBLAST programs (version 2.0) of Altschul et al. J. Mol. Biol. 215:403-10, 1990. BLAST nucleotide searches can be performed with the NBLAST program, score=100, wordlength-12 to obtain guide sequences homologous to a target nucleic acid. Where gaps exist between two sequences, Gapped BLAST can be utilized as described in Altschul et al., Nucleic Acids Res. 25(17):3389-3402, 1997. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (e.g., XBLAST and NB LAST) can be used.

The polynucleotides provided herein, such as RNAi molecules targeting IAP, in some embodiments, are designed to have at least one silencing element complementary (e.g., wholly (100%) or partially (less than 100%, e.g., 90% to 99%) complementary) to a segment of a sequence of IAP mRNA of a Coleopteran insect, e.g., a Colorado potato beetle. In some embodiments, polynucleotides comprise at least one silencing element that is essentially identical or essentially complementary to IAP mRNA of a Coleopteran insect. In some embodiments, the polynucleotides comprise 2 to 5, to 10, 2 to 20, 2 to 20, 2 to 40, or 2 to 50 silencing elements. In some embodiments, the polynucleotides comprise at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, at least 40, at least 45 or at least 50 silencing elements.

RNAi molecules targeting IAP provided herein may be of any form of RNA, including single-stranded RNA (ssRNA) and double-stranded RNA (dsRNA). Non-limiting examples of single-stranded RNA include mRNA, micro RNA (miRNA) (e.g., artificial miRNA (amiRNA)), small interfering RNA (siRNA), piwi-interacting RNA (piRNA), and antisense RNA. Double-stranded RNA includes wholly double-stranded molecules that do not contain a single-stranded region (e.g., a loop or overhang), as well as partially double-stranded molecules that contain a double-stranded region and a single-stranded region (e.g., a loop or overhang). Further, the RNAi molecules may be single-stranded RNA molecules with secondary structure containing significant double-stranded character, such as, but not limited to, hairpin RNA. Thus, RNAi molecules targeting IAP, in some embodiments, may be short hairpin RNA (shRNA).

In some embodiments, RNAi molecules targeting IAP comprise dsRNA, ssRNA, siRNA, miRNA (e.g., amirRNA), piRNA, mRNA, or shRNA. In some embodiments, RNAi molecules targeting IAP comprise more than one form of RNA. For example, the RNAi molecules targeting IAP may comprise ssRNA and dsRNA. In some embodiments, RNAi molecules targeting IAP comprise a hybrid with RNA and DNA. In some embodiments, RNAi molecules targeting IAP comprise amiRNAs processed from a long precursor transcript of nonprotein-coding RNA, that is partially self-complementary to mediate silencing of target mRNAs. amiRNAs are designed, in some embodiments, by replacing the mature 21 nucleotide miRNA sequences within pre-miRNA with 21 nucleotide long fragments derived from the target gene (Frontiers in Plant Science, Sebastian et al., 2017). An amiRNA may have a length of, for example, at least 18 to 500 nucleotides, at least 21 to 500 nucleotides, at least 50 to 500 nucleotides, at least 100 to 500 nucleotides, or at least 200 to 500 nucleotides.

RNAi molecules targeting IAP may be provided as a mixture of RNAi molecules targeting IAP, for example, a mixture of RNAi molecules targeting IAP having different sequences. Any number of distinct RNAi molecules targeting IAP may be provided in a mixture of RNAi molecules targeting IAP. In some embodiments, the mixture of RNAi molecules targeting IAP comprises at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or at least 10 distinct (having different sequences/nucleotide compositions) RNAi molecules targeting IAP.

In some embodiment, RNAi molecules targeting IAP are provided as a mixture of RNAi molecules that are complementary (wholly or partially) to different segments of an mRNA encoded by an IAP gene (e.g., comprising a sequence of SEQ ID NO: 1). In some embodiment, RNAi molecules targeting IAP are provided as a mixture of RNAi molecules that are complementary (wholly or partially) to different segments of an RNA sequence of SEQ ID NO: 19. Any number of RNAi molecules targeting IAP that are complementary to different segments of an mRNA (e.g., comprising a sequence of SEQ ID NO: 19) encoded by an IAP gene (e.g., comprising a sequence of SEQ ID NO: 1) may be provided in a mixture of RNAi molecules targeting IAP. In some embodiments, the mixture of RNAi molecules targeting IAP comprises at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, or at least 10 RNAi molecules targeting IAP. In some embodiments, the mixture of RNAi molecules targeting IAP comprises 2 to 5, or 2 to 10 RNAi molecules targeting IAP.

In some embodiments, RNAi molecules targeting IAP provided herein may have one or more mismatches compared with the corresponding sequence of IAP mRNA (e.g., SEQ ID NO: 19). A region of complementarity on RNAi molecule targeting IAP may have up to 1, up to 2, up to 3, up to 4, etc. mismatches provided that it maintains the ability to form complementary base pairs with IAP mRNA under appropriate hybridization conditions. Alternatively, a region of complementarity on RNAi molecules targeting IAP may have no more than 1, no more than 2, no more than 3, or no more than 4 mismatches provided that it maintains the ability to form complementary base pairs with IAP mRNA under appropriate hybridization conditions. In some embodiments, if there is more than one mismatch in a region of complementarity, they may be positioned consecutively (e.g., 2, 3, 4, or more in a row), or interspersed throughout the region of complementarity provided that the RNAi molecule targeting IAP maintains the ability to form complementary base pairs with IAP mRNA under appropriate hybridization conditions.

RNAi molecules targeting IAP may be modified in various ways to improve or control specificity, stability, delivery, bioavailability, degradation, resistance to nuclease degradation, base-pairing properties, RNA distribution, and cellular uptake, and other features relevant to its use. See, e.g., Bramsen et al., Nucleic Acids Res., 2009, 37, 2867-2881; Bramsen and Kjems, Frontiers in Genetics, 3 (2012): 1-22. Accordingly, in some embodiments, RNAi molecules targeting IAP may include one or more (at least one) suitable modifications. In some embodiments, a modified RNAi molecule targeting IAP has a modification in its base, sugar (e.g., ribose, deoxyribose), or phosphate group.

RNAi molecules targeting IAP produced by the methods provided herein may be modified as described herein. In some embodiments, RNAi molecules targeting IAP is produced according to a method described herein and subsequently modified. In some embodiments, RNAi molecules targeting IAP are produced according to a method described herein using a modified starting material. In some embodiments, the modified starting material is a modified nucleobase. In some embodiments, the modified starting material is a modified nucleoside. In some embodiments, the modified starting material is a modified nucleotide.

In some embodiments, modified RNAi molecules targeting IAP comprise a backbone modification. In some embodiments, backbone modification results in a longer half-life for the RNA due to reduced degradation (e.g., nuclease-mediated degradation). This in turn results in a longer half-life. Examples of suitable backbone modifications include, but are not limited to, phosphorothioate modifications, phosphorodithioate modifications, p-ethoxy modifications, methylphosphonate modifications, methylphosphorothioate modifications, alkyl- and aryl-phosphates (in which the charged phosphonate oxygen is replaced by an alkyl or aryl group), alkylphosphotriesters (in which the charged oxygen moiety is alkylated), peptide nucleic acid (PNA) backbone modifications, and locked nucleic acid (LNA) backbone modifications. These modifications may be used in combination with each other and/or in combination with phosphodiester backbone linkages.

Alternatively or additionally, RNAi molecules targeting IAP may comprise other modifications, including modifications at the base or sugar moiety. Examples include RNA having sugars that are covalently attached to low molecular weight organic groups other than a hydroxyl group at the 3′ position and other than a phosphate group at the 5′ position (e.g., a 2′-O-alkylated ribose), or RNA having sugars such as arabinose instead of ribose. RNA also embraces substituted purines and pyrimidines such as C-5 propyne modified bases (Wagner et al., Nature Biotechnology 14:840-844, 1996). Other purines and pyrimidines include, but are not limited to, 5-methylcytosine, 2-aminopurine, 2-amino-6-chloropurine, 2,6-diaminopurine, and hypoxanthine. Other such modifications are well known to those of skill in the art.

RNAi molecules that comprise a nucleotide sequence complementary to all or a segment of the target sequence can be designed and prepared using any suitable methods. In some embodiments, an RNAi molecule may be designed with assistance from comprehensive sequence databases, such as those known for Tribolium and Drosophila genetics (e.g., Flybase, SnapDragon, Beetlebase, etc.). In some embodiments, a sequence database is utilized to determine off-target effects of a designed RNAi molecule (e.g., as in Arziman, Z., Horn, T., & Boutros, M. (2005).

Methods of Use

Aspects of the present disclosure, in some embodiments, provide methods for controlling a Coleopteran insect infestation comprising delivering to a plant or Coleopteran insect (e.g., Colorado potato beetle) an effective amount of an RNAi molecule targeting TAP (or a composition comprising an RNAi molecule targeting TAP). In some embodiments, the method of delivery comprises applying to a surface of a plant or Coleopteran insect, a composition comprising the RNAi molecule. In some embodiments, a composition comprising an RNAi molecule targeting IAP is a solid or liquid (e.g., solution, suspension, or emulsions). Non limiting examples include emulsifiable concentrates, concentrate solutions, low concentrate solutions, ultra-low volume concentrate solutions, water soluble concentrate solutions, water soluble liquid solutions, baits (paste, gel, liquid, solid or injectable), smoke, fog, invert emulsions, flowables, aerosols, homogenous and non-homogenous mixtures, suspensions (water and oil based), dust, powders (wettable or soluble), granules (water-dispersible or dry flowables), pellets, capsules, fumigants, encapsulated or micro-encapsulation formulations, or any combinations thereof.

In some embodiments, a compositing comprising an RNAi molecule targeting IAP may be applied as a concentrate, spray (after dilution or concentrate), fog, in furrow, seed treatment, drench, drip, insect diet, bait, or any other forms suited for applying to a furrow. The RNAi molecule targeting IAP described herein may be delivered to any portion of a plant, including, but are not limited to, leaf, stem, flower, fruit, shoot, root, seed, tuber, anther, stamen, and/or pollen. In some embodiments, RNAi is delivered mechanically, through high pressure spray or sand blasting. In some embodiments, a composition comprises an RNAi molecules and at least one additive selected from adjuvants, attractants, sterilizing agents, growth-regulating substances, carriers or diluents, stabilizers, and/or pesticidal agent(s) (e.g., insecticides, fungicides, and/or herbicides). Pesticidal agents include, for example, other dsRNA targeting genes distinct from IAP, patatins, plant lectins, phytoecdysteroids, cry proteins, vegetative insecticidal proteins (vip), cytolytic proteins (cyt), biotin-binding proteins, protease inhibitors, chitinases, organic compounds, or any combination thereof. Non-pesticidal agents may also be used (e.g. adjuvants, such as antifoaming agents, buffers, compatibility agents, drift control additives, emulsifiers, extenders, invert emulsifiers, plant penetrants, safeners, spreaders, stickers, surfactants, thickeners, and wetting agents).

A composition, in some embodiments, include a mixture of an RNAi molecule targeting IAP and at least one of a variety of agricultural chemicals, insecticides, miticides, fungicides, pesticidal agents

In some embodiments, an RNAi molecule targeting IAP is supplied in the diet of a Coleopteran insect. For example, an RNAi molecule targeting IAP may be applied topically to a plant, or seeds (e.g. via soaking, coating, dusting or spraying), or cells of a plant may be engineered to express the RNAi molecule. RNAi molecules may also be supplied in another food or water source.

The plant may be any plant that is subject to infestation by a Coleopteran insect. In some embodiments, the plant is a Solanaceous plant (e.g., family Solanaceae). Examples of Solanaceous plants include, but are not limited to, potato plants (Solanum tuberosum), buffalo bur plants (Solanum rostratum), eggplant plants (Solanum melongena), tomato plants (Solanum lycopersicum), tobacco plants (Nicotiana tabacum), pepper plants (Capsicum annum) and woody nightshade plants (Solanum dulcamara).

Thus, in some embodiments, the methods comprise delivering to a plant (e.g., a potato plant) with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle). In other embodiments, the methods comprise delivering to a buffalo bur plant with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle). In yet other embodiments, the methods comprise delivering to an eggplant plant with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle). In still other embodiments, the methods comprise delivering to a tomato plant with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle). In further embodiments, the methods comprise delivering to a tobacco plant with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle). In additional embodiments, the methods comprise delivering to a pepper plant with an RNAi molecule targeting IAP, for example, in an effective amount to suppress infestation of the plant by a Coleopteran insect (e.g., Colorado potato beetle).

Delivering to a plant (e.g., a part of a plant) and/or Coleopteran insect an RNAi molecule targeting IAP may include, for example, applying (e.g., soaking, coating, or dusting) the RNAi molecule or a composition comprising the RNAi molecule topically to any portion of a plant (e.g., roots, tubers, stem, branches, leaves, flower, etc.), ground (e.g., soil, dirt, grass, etc.), insect and/or diet of the insect. A delivering step may also include genetically engineering cells of a plant to express the RNAi molecule. A delivering step may also include exposing a plant or Coleopteran insect to an organism (e.g., virus, bacteria, fungus, etc.) that has been genetically engineered to express and/or deliver the RNAi molecule to the plant or Coleopteran insect.

An effective amount is the amount of an RNAi molecule targeting IAP required to confer a beneficial effect on infestation (e.g. death, cessation of feeding, inhibition of growth, development or reproduction) by a Coleopteran insect, either alone or in combination with one or more other additives. Beneficial effects include a reduction in infestation, for example, by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90%, relative to a control. In some embodiments, the control is the absence of an insecticide and/or pesticide. In some embodiments, an effective amount of an RNAi molecule targeting IAP completely eliminates Coleopteran insect (e.g., Colorado potato beetle) infestation of a plant.

Effective amounts vary, as recognized by those skilled in the art, depending on the particular plant, the severity of the infestation, the duration of the infestation, previous exposure to insecticides and like factors within the knowledge and expertise of a practitioner. These factors are well known to those of ordinary skill in that art and can be addressed with no more than routine experimentation. It is generally preferred that lower effective concentrations be used, that is, the lowest concentration that provides control of an insect, to increase efficiency and decrease cost.

An effective amount of an RNAi molecule targeting IAP may also vary depending on the method of delivery.

In some embodiments, an effective amount of an RNAi molecule targeting IAP is expressed as micrograms (μg) of RNAi molecule targeting IAP per centimeter squared (cm²) of a surface of a plant or ground (e.g., soil, dirt, grass, etc.), i.e., μg/cm². Thus, in some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.001 μg/cm² to 10 μg/cm². In some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.001 μg/cm² to 9 μg/cm², 0.001 μg/cm² to 8 μg/cm², 0.001 μg/cm² to 7 μg/cm², 0.001 μg/cm² to 6 μg/cm², 0.001 μg/cm² to 5 μg/cm², 0.001 μg/cm² to 4 μg/cm², 0.001 μg/cm² to 3 μg/cm², 0.001 μg/cm² to 2 μg/cm², 0.001 μg/cm² to 1 μg/cm², 0.001 μg/cm² to 0.1 μg/cm², or 0.001 μg/cm² to 0.01 μg/cm². In some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.01 μg/cm² to 10 μg/cm², 0.1 μg/cm² to 10 μg/cm², 1 μg/cm² to 10 μg/cm², 2 μg/cm² to 10 μg/cm², 3 μg/cm² to 10 μg/cm², 4 μg/cm² to 10 μg/cm², 5 μg/cm² to 10 μg/cm², 6 μg/cm² to 10 μg/cm², 7 μg/cm² to 10 μg/cm², 8 μg/cm² to 10 μg/cm², or 9 μg/cm² to 10 μg/cm².

In some embodiments, an effective amount of an RNAi molecule targeting IAP is expressed as grams (g) of RNAi molecule targeting IAP per acre (ac.) of a surface of a plant or ground (e.g., soil, dirt, grass, etc.), i.e., g/ac. Thus, in some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.01 g/ac. to 100 g/ac. In some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.01 g/ac. to 90 g/ac., 0.01 g/ac. to 80 g/ac., 0.01 g/ac. to 70 g/ac., 0.01 g/ac. to 60 g/ac., 0.01 g/ac. to 50 g/ac., 0.01 g/ac. to 40 g/ac., 0.01 g/ac. to 30 g/ac., 0.01 g/ac. to 20 g/ac., 0.01 g/ac. to 10 g/ac., 0.01 g/ac. to 1 g/ac., or 0.01 g/ac. to 0.1 g/ac. In some embodiments, an effective amount of an RNAi molecule targeting IAP comprises 0.1 g/ac. to 100 g/ac., 1 g/ac. to 100 g/ac., 10 g/ac. to 100 g/ac., 20 g/ac. to 100 g/ac., 30 g/ac. to 100 g/ac., 40 g/ac. to 100 g/ac., 50 g/ac. to 100 g/ac., 60 g/ac. to 100 g/ac., 70 g/ac. to 100 g/ac., 80 g/ac. to 100 g/ac., or 90 g/ac. to 100 g/ac.

In some embodiments, the effectiveness of an RNAi molecule to control Coleopteran insects can be determined using the ability of the RNAi molecule to kill or cause death of an insect or population of insects. The rate of death in a population of insects may be determined by percent mortality (e.g., percent mortality over time). Generally, percent mortality of a population of insects reflects the percentage of insects in said population that have died as a result of the RNAi molecule (e.g., 75% mortality indicates that an RNAi molecule has killed 75% of the total insect population). In some embodiments, percent mortality is measured over time (e.g., over the course of a multi-day exposure of insects to an RNAi molecule). In some embodiments, percent mortality is measured after at least 3, 4, 5, 6, 7, 8, 9, 10, 15, or 20 days of exposure. In some embodiments, an RNAi molecule causes a percent mortality of at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98%, or 100% of a Coleopteran insect population. In some embodiments, at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98%, or 100% of a Coleopteran insect population are killed by an RNAi molecule that targets IAP. In some embodiments, percent mortality of an RNAi molecule is compared to a control (e.g., a control molecule or untreated conditions). In some embodiments, percent mortality of an RNAi molecule is at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 120%, 150%, or 200% higher than a control (e.g., a control molecule or untreated conditions).

In some embodiments, the effectiveness of an RNAi molecule to control Coleopteran insects can be determined using the ability of the RNAi molecule to limit the leaf disc consumption of a Coleopteran insect or an insect population. Leaf disc consumption refers to the amount (e.g., percentage) of plant material (e.g., an eggplant leaf) that is consumed or eaten by an insect or population of insects. In some embodiments, an RNAi molecule causes at least a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98%, or 100% decrease in the leaf disc consumption by an insect or population of insects. In some embodiments, the ability of an RNAi molecule to decrease leaf disc consumption is compared relative to a control (e.g., a control molecule or untreated conditions). In some embodiments, leaf disc consumption is measured over time (e.g., over the course of a multi-day exposure of insects to an RNAi molecule). In some embodiments, leaf disc consumption is measured after 3, 4, 5, 6, 7, 8, 9, 10, or more days of exposure.

In some embodiments, the effectiveness of an RNAi molecule to control Coleopteran insects can be determined using the ability of the RNAi molecule to decrease percent plant defoliation by a Coleopteran insect or an insect population. Percent plant defoliation refers to the percentage of plant material (e.g., an eggplant leaf) that is destroyed (e.g., consumed) by an insect or population of insects. In some embodiments, an RNAi molecule causes at least a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, 98%, or 100% decrease in the percent plant defoliation by an insect or population of insects. In some embodiments, an RNAi molecule causes percent plant defoliation to decrease below 40%, 30, 25%, 20%, 15%, 10%, 5%, 3%, or 1%. In some embodiments, percent plant defoliation remains below 40%, 30, 25%, 20%, 15%, 10%, 5%, 3%, or 1% for at least 5, 6, 7, 8, 9, 10, 15, or 20 days following exposure of insects to an RNAi molecule. In some embodiments, the ability of an RNAi molecule to decrease percent plant defoliation is compared relative to a control (e.g., a control molecule or untreated conditions). In some embodiments, percent plant defoliation is measured over time (e.g., over the course of a multi-day exposure of insects to an RNAi molecule). In some embodiments, percent plant defoliation is measured after 3, 4, 5, 6, 7, 8, 9, 10, or more days of exposure.

In some embodiments, an RNAi molecule targeting IAP may be formulated in a solution (e.g., that is applied to a surface of the Coleopteran insect and/or diet (e.g., food and/or water ingested), a plant or ground (e.g., soil, dirt, grass, etc.)). In some embodiments, the effective amount of the RNAi molecule targeting IAP in the solution is expressed as nanograms (ng) or micrograms (μg) of RNAi molecule targeting IAP per milliliter (ml) of the solution, i.e., ng/ml. Thus, in some embodiments, a solution comprises an RNAi molecule targeting IAP at a concentration of 10 ng/ml to 100 μg/ml.

In some embodiments, an RNAi molecule targeting IAP is provided in a diet of an insect. Thus, in some embodiments, an effective amount of an RNAi molecule targeting IAP is expressed as micrograms (μg) of RNAi molecule targeting IAP per milliliter (ml) of the diet of the insect, i.e., μg/ml. In some embodiments, the diet of an insect comprises an RNAi molecule targeting IAP at a concentration of 0.001 μg/ml to 10 μg/ml.

The step of delivering to any portion of a plant (e.g., roots, tubers, stem, branches, leaves, flower, etc.), ground (e.g., soil, dirt, grass, etc.), insect and/or diet of the insect with an RNAi molecule targeting IAP may include a single application (single contact) or multiple applications (multiple contacts) of the RNAi molecule targeting IAP to the plant, ground (e.g., soil, dirt, grass, etc.), insect and/or diet of the insect. Delivery to a portion of a plant, insect and/or diet of the insect may be in the form of a spray (e.g., pressurized/aerosolized spray, pump) solid, (e.g. powder, pellet, bait), or liquid (e.g., homogeneous mixtures such as solutions and non-homogeneous mixtures such as suspensions (water and oil based), colloids, micelles, and emulsions). The period of time of contact may vary. In some embodiments, delivering comprises an exposure of an RNAi molecule targeting IAP with a portion of a plant and/or Coleopteran insect for a suitable period sufficient for reduction of growth, reproduction (e.g., fertility and/or fecundity), and/or feeding of the Coleopteran insect and/or death of the Coleopteran insect, if any.

In some embodiments, delivery of an RNAi molecule targeting IAP with a plant and/or Coleopteran insect is followed by ingestion and/or absorption of the RNAi molecule targeting IAP by the plant and/or Coleopteran insect. In some embodiments, ingestion of the RNAi molecule targeting IAP by the Coleopteran insect alters a biological function of the Coleopteran insect, thereby controlling infestation by the Coleopteran insect. Examples of altered biological function of the Coleopteran insect include, but are not limited to, reduced growth, reduced reproduction (e.g., fertility and/or fecundity), reduced feeding, decreased movement, decreased development, decreased cellular repair, and/or increased mortality.

In some embodiments, delivering comprises applying an RNAi molecule targeting IAP to a portion of the surface of a plant and/or a surface contacted by a Coleopteran insect (e.g., ground (e.g., soil, dirt, grass, etc.)). In some embodiments, applying an RNAi molecule targeting IAP to a portion of a surface comprises spraying, coating, and/or dusting the surface or portion thereof. In some embodiments, applying an RNAi molecule targeting IAP RNA to a portion of a surface comprises ground drenching or applying the RNAi molecule as a granulated or powdered formulation to the soil adjacent to the roots of the plant.

A RNAi molecule targeting IAP may be applied to any portion of a plant (e.g., roots, tubers, stem, branches, leaves, flower, etc.). In some embodiments, the RNAi molecule targeting IAP is contacted with an above-ground portion of a plant (e.g., a leaf) and/or with a below-ground portion of a plant (e.g., a root), which may include at least one in furrow formulation selected from the group consisting of a powder, granule, pellet, capsule, soluble liquid concentrate, spray (after dilution or concentrate), fog, in furrow, seed treatment, insect diet, bait, drench, drip irrigation, or any other forms suited for applying to a furrow. Portions of a plant that may be contacted with the RNAi molecule targeting IAP described herein include, but are not limited to, leaf, stem, flower, fruit, shoot, root, seed, tuber, anther, stamen, or pollen. In some embodiments, RNAi is delivered mechanically, through high pressure spray or sand blasting.

In some embodiments, delivering comprises providing an RNAi molecule targeting IAP for dietary uptake by the Coleopteran insect. In some embodiments, contacting comprises providing an RNAi molecule targeting IAP that can be ingested or otherwise absorbed internally by the Coleopteran insect. In some embodiments, the RNAi molecule targeting IAP is provided in a diet for dietary uptake by the Coleopteran insect. In some embodiments, the RNAi molecule targeting IAP is provided in/on a plant or plant part, or topically applied to a plant or plant part (e.g., soaking, coating, dusting). In some embodiments, the RNAi molecule targeting IAP is expressed in a plant or plant part.

In some embodiments, delivering an RNAi molecule targeting IAP to a Coleopteran insect inhibits expression of (reduces or inhibits expression of) an endogenous complementary nucleotide sequence (e.g., RNA sequence) in the Coleopteran insect. In some embodiments, the endogenous complementary nucleotide sequence is an endogenous IAP sequence.

Consequences of inhibition can be confirmed by any appropriate assay to evaluate one or more properties of an insect, or by biochemical techniques that evaluate molecules indicative of IAP expression (e.g., RNA, protein). In some embodiments, the extent to which an RNAi molecule targeting IAP provided herein reduces levels of expression of IAP is evaluated by comparing expression levels (e.g., mRNA or protein levels of IAP to an appropriate control (e.g., a level of IAP expression in a cell or population of cells to which an RNAi molecule targeting IAP has not been delivered or to which a negative control has been delivered). In some embodiments, an appropriate control level of IAP expression may be a predetermined level or value, such that a control level need not be measured every time. The predetermined level or value can take a variety of forms. In some embodiments, a predetermined level or value can be single cut-off value, such as a median or mean.

In some embodiments, delivering an RNAi molecule targeting IAP as described herein results in a reduction in the level of IAP expression in a cell of an insect. In some embodiments, the reduction in levels of IAP expression may be a reduction by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% relative to a control level. In some embodiments, the control level is a level of IAP expression in a similar insect cell (or average level among a population of cells) not contacted with the RNAi molecule. In some embodiments, the control level is a level of IAP expression in a similar insect cell (or average level among a population of cells) contacted with an RNAi molecule targeting a gene not expressed by the insect cell, e.g., green fluorescent protein (GFP).

In some embodiments, the effect of delivering to a cell or insect an RNAi molecule targeting IAP is assessed after a finite period of time. For example, levels of IAP may be determined in a cell or insect at least 4 hours, 8 hours, 12 hours, 18 hours, 24 hours; or at least one, two, three, four, five, six, seven, or fourteen days after delivering to the cell or insect the RNAi molecule targeting IAP.

In some embodiments, delivery of an RNAi molecule targeting IAP as described herein results in a reduction in the level of growth, reproduction (e.g., fertility and/or fecundity), and/or feeding of an insect. In some embodiments, the reduction in levels of growth, reproduction (e.g., fertility and/or fecundity), and/or feeding may be a reduction by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% relative to a control level. In some embodiments, the control level is a level of growth, reproduction (e.g., fertility and/or fecundity), and/or feeding of a similar insect not contacted with the RNAi molecule. In some embodiments, the control level is a level of growth, reproduction (e.g., fertility and/or fecundity), and/or feeding of a similar insect contacted with an RNAi molecule targeting a gene not expressed by the insect cell, e.g., green fluorescent protein (GFP).

In some embodiments, delivery of an RNAi molecule targeting IAP as described herein results in an increase in mortality among a population of insects. In some embodiments, the increase in level of mortality may be an increase by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 98%, at least 99%, or 100% relative to a control. In some embodiments, the control is mortality among a population of insects not contacted with the RNAi molecule. In some embodiments, the control is among a population of insects contacted with an RNAi molecule targeting a gene not expressed by the insect cell, e.g., green fluorescent protein (GFP).

Example 1: IAP RNAi Composition Kills Colorado Potato Beetles

To evaluate the effect of the IAP RNAi polynucleotide (SEQ ID NOS: 21 and 39) on Colorado potato beetles (CPBs), a composition (e.g., comprising water) comprising a IAP RNAi polynucleotide (hereafter, “G53”) was treated (at a concentration of 10 μg/cm²) onto the leaves of potato plants. Up to 90% of CPBs died following a 9-day exposure to the GS3-covered potato plant leaves, compared with less than 10% of CPBs that die following exposure to the negative control (GS4) leaves (FIG. 1A). This increased mortality in response to exposure to GS3 also results in a decrease of potato leaf consumption to nearly 0% (FIG. 1B). Percent potato leaf consumption refers to the percentage of potato leaf discs (punched out of potato leaves) following treatment of the discs with the RNAi composition and subsequent exposure of the discs to Colorado potato beetle, for example.

A dose-titration of the GS3 composition was also performed to determine if a lower concentration of the IAP RNAi polynucleotide is equally effective in controlling CPBs. Up to 90% of CPBs died following a three-day exposure to GS3 at 1.0 μg/cm² and 0.1 μg/cm², about 70% of CPBs died following a three-day exposure to GS3 at 0.01 μg/cm², and about 15% of CPBs died following a three-day exposure to GS3 at 0.001 μg/cm² compared to a control (GS4) composition at 1.0 μg/cm² (FIG. 2A). Potato leaf consumption also decreased to nearly 0% when CPBs were exposure to GS3 at 1.0 μg/cm² and 0.1 μg/cm², while CPBs exposed to GS3 at 0.01 μg/cm² only consumed about 20% of potato leaves, and CPBs exposed to GS3 at 0.001 μg/cm² consumed about 60% of potato leaves (FIG. 2B).

Exposure of CPBs to the IAP RNAi polynucleotide administered to potato leaves at a concentration of as low as 0.1 μg/cm² results in a 90% mortality and a 95% decreased potato leaf consumption compared to CPBs exposed to a control.

Example 2: Application of IAP RNAi Composition to Plants Controls Colorado Potato Beetles

The composition comprising IAP RNAi polynucleotide (GS3) of Example 1 was tested for its effectiveness in controlling the numbers of Colorado potato beetles (CPBs) on a potato plant. Briefly, the GS3 composition (e.g., 0.06 g/L), a composition comprising CORAGEN® (+control; an agent known to kill CPBs), or no treatment (−control) was applied to the leaves of potato plants. The effect of irrigation (approximately 500 ml of water per plant, simulating ½ inch of rain), on GS3 composition efficacy was also tested. The number of CPB larvae per plant was decreased by about 90% in potato plants treated with GS3, regardless of irrigation, relative to untreated potato plants (FIG. 3A). The percent of potato plant defoliation was also decreased by about 90% when the plants were treated with GS3, regardless of irrigation, relative to untreated potato plants (FIG. 3B).

Exposure of CPBs to the IAP RNAi polynucleotide in the GS3 composition administered to potato plants decreased the numbers of live larvae per plant and plant defoliation by about 90% compared to CPBs exposed to potato plants that were untreated.

Example 3: IAP RNAi Compositions Spanning the Length of the IAP Gene are Effective at Controlling Colorado Potato Beetle (CPB) Infestation

Four dsRNA molecules that collectively bind to the entire length of messenger RNA (mRNA) (SEQ ID NO: 19) encoded by a Coleopteran IAP gene (SEQ ID NO: 1) were evaluated for their effectiveness to control Colorado potato beetle (CPB) infestation. The dsRNA molecules used in this Example were: GS3, GS167, GS168, GS169, and the negative control molecule (GS4).

For each dsRNA, four leaves (˜20 days old) were cut from an eggplant plant, coated with 0.5 μg/μL of dsRNA, and dried for about 30 min. Each of the four leaves was placed into four different Petri dishes (100 mm×15 mm) on a moisture filter paper. For each petri dish, five ‘second instar’ CPB larvae were placed on top of each leaf and the dishes kept at room temperature. On Day 3 (after 72 hours) and Day 6 (after 144 hours), new dsRNA-treated leaves were placed into the Petri dishes. The total number of CPB insects was counted in each experiment on Days 3, 6, 7, 8, and 9. For purposes of determining mortality caused by each dsRNA, the initial count of living CPB insects was established on Day 2. Any CPB insects that were already dead on Day 2 were assumed to be dead because of handling conditions or initial insect health conditions. Each dsRNA experiment was duplicated using different batches of insects on different weeks, each comprising four different leaf Petri dishes).

All of tested dsRNA molecules (GS3, GS167, GS168, and GS169) that bind to an mRNA encoded by a Coleopteran IAP gene caused significant time-dependent mortality in CPB insects (Tables 1-2). After nine days of exposure, GS3 caused an average 93% mortality in CPB insects; GS167 caused an average 91% mortality in CPB insects; GS168 caused an average 83% mortality in CPB insects; and GS168 caused an average 69% mortality in CPB insects. Conversely, the negative control (GS4) only caused an average 26% mortality (FIG. 5).

Example 4: IAP RNAi Compositions of Minimal Length (49-200 Nucleotides) are Effective at Controlling Colorado Potato Beetles

Five dsRNA molecules comprising sequences of minimal length (49-200 nucleotides) that bind to a messenger RNA (mRNA) (e.g., SEQ ID NO: 19) encoded by a Coleopteran IAP gene (e.g., SEQ ID NO: 1) were evaluated for their effectiveness to control Colorado potato beetles (CPBs). The evaluated dsRNA molecules were: GS176, GS177, GS178, GS179, GS180, GS3, and the negative control (GS4).

GS176, GS177, and GS178 were tested with GS4 and GS3 according to the procedure described in Example 3.

GS179 and GS193 were tested with GS4 and GS3 at a concentration of 0.027 μg/μL using twelve eggplant leaves, each with a single ‘second instar’ CPB larvae. GS179 and GS180 comprised sequences of complementarity to IAP mRNA flanked by a T7 promoter and a restriction site.

All of tested dsRNA molecules comprising 100-200 nucleotides that bind to an mRNA encoded by a Coleopteran TAP gene (GS176, GS177, GS178) caused significant time-dependent mortality in CPB insects (Table 2). After nine days of exposure, the 200-nucleotide length dsRNA molecule (GS176) caused an average 89% mortality in CPB insects; the 150-nucleotide length dsRNA molecule (GS177) caused an average 95% mortality in CPB insects; and the 100-nucleotide length dsRNA molecule (GS178) caused an average 89% mortality in CPB insects. Each of these three dsRNA molecules functioned to control/kill CPB insects at similar levels as the 432-nucleotide length dsRNA molecule (GS3). Conversely, the negative control (GS4) only caused an average 26% mortality (FIG. 6A).

The dsRNA molecules comprising 49 nucleotides (GS179) and 74 nucleotides (GS193), respectively, caused time-dependent mortality in CPB insects (Table 5). After eight days of exposure, the 49-nucleotide length dsRNA molecule (GS179) caused an average 56% mortality in CPB insects; and the 74-nucleotide length dsRNA molecule (GS180) caused an average 60% mortality in CPB insects. The negative control (GS4) caused an average 10% mortality (FIG. 6B).

Example 6: An Example IAP RNAi Composition Controls Colorado Potato Beetles in Field Trials

The 432-nucleotide dsRNA (GS3) that binds to a messenger RNA (mRNA) encoded by a Coleopteran TAP gene was evaluated for its ability to control CPB insects in three open-air field trials. Briefly, in each field trial, a composition comprising GS3 (2-4 grams/acre), one or more positive control composition(s) (standards) comprising CORAGEN® (73 grams/acre), ENTRUST® (88 grams/acre), and/or NOVODOR™ (161 M Bio En/ha), or no treatment (negative control) was applied to the leaves of potato or eggplant plants in an open field. Each RNAi composition (GS3) was applied to the leaves either in four applications on a five-day interval, or three applications on a seven-day interval. The standards were applied to the leaves in three applications on seven-day intervals (Days 0, 7, and 14). Percent defoliation of the potato leaves was assessed at 2, 6, 13 and 20 days after the first application, and percent defoliation of the eggplant leaves was assessed at 5, 14, and 21 days after the first application.

In field trial #1 (FIG. 9A), potato plants that were untreated were 39% defoliated at Day 20. Conversely, potato plants treated with GS3 were 10% defoliated at Day 20; plants treated with standards (e.g. CORAGEN® and ENTRUST®) were less than 5% defoliated at Day 20.

In field trial #2 (FIG. 9B), potato plants that were untreated were 48% defoliated at Day 20. Conversely, potato plants treated with GS3 were approximately 10% defoliated at Day 20; plants treated with standards (e.g. CORAGEN®, ENTRUST®, NOVODOR™) were less than 5% defoliated at Day 20.

In field trial #3 (FIG. 9C), eggplant plants that were untreated were 45% defoliated at Day 21. Conversely, eggplant plants treated with GS3 were 15% defoliated at Day 21 and plants treated with standards (e.g. CORAGEN® and ENTRUST®) were less than 10% defoliated at Day 21.

These data demonstrate that application of IAP RNAi compositions of the disclosure prevent defoliation of plants (e.g., potato or eggplant plants) when applied to the leaves of plants in open fields (e.g., fields of crops).
